To a/ZZ whom t mar/'y concern:

Be it known that we, OLIVER COLBORNE and FRED DEUERLING, citizens of the United States of America, and residents of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pie-Machines, of which the following is a specification.

This invention relates to pie-making machinery, and its main objects are to provide an improved arrangement of the conveyer of the pie-making machine whereby the mechanism will be compactly situated and whereby the pie-tins will at all times be carried in positions in which they may be readily operated upon, to provide an improved form of pie-crust-rolling device which is adapted to be located within the path of the horizontally-disposed conveyer, and to deliver piecrusts toward opposite points along said path. These objects are accomplished by the device shown in the accompanying drawings, in which- Figure 1 is a top plan of a pie-machine constructed according to this invention. Flg. 2 is an end elevation of the crust-rollingmechanism, the supporting-platform being shown in section and the conveyer being omitted. Fig. 3 is an elevation of the same Aviewed from the side which is at the left in Fig. 2.

In the construction shown in the drawings the main supporting-frame is provided with an elongated horizontally-disposed platform 1 at the top. The supporting structure and the mechanism below the platform 1 for operating the conveyer are omitted from the drawings, since they do not form a part ofthe present invention. Journaled in the frame on vertically-disposed axes and immediately below the platform 1 are two sprocket-wheels or sets of sprocket-wheels 2, which carry an endless link-belt conveyer 3. This'eonveyer is arranged to travel in a horizontal plane around the edges of the table l. The conveyer is providedwith a plurality of carriers spaced at equal distance around the conveyer and each adapted to support a pie-tin, as indicated at 4 in the drawings. A crust-trimming device 5 is located at one end of the table 1 and is adapted to trim the crusts of a pie delivered beneath the same by the conveyer. The conveyer is driven intermittently, so that each of the pie-tins is stopped in each of the positions in which such tins are frame 6, secured upon the platform 1 at av pointV intermediate of its ends and provided with brackets 7, overhanging the conveyer' 3 at each side of the platform. Each of the brackets 7 has journaled therein a' pair of horizontally-disposed rollersS, 9, 10, and 11. Said rollers are disposed one above the other in each case, and their axes are disposed'at right angles to the adjacent part of the path of the pie-tin. A pair of horizontally-disposed shafts 12 and 13 are journaled 1n the frame 6 in the same plane with each other, but at a level considerably higher than that of the rollers 8 and 10. Each of these shafts is provided with a pair of rollers 14. and 15, and the opposed rollers are driven at equal peripheral speeds and in opposite directions by means of the gears 16. Power is supplied from the shaft 17 and transmitted therefrom by spur-gears 18 and 19 to the shaft 13. Power is transmitted from the shaft 13 to the shaft 20 of the roller 8 by means of spiral gears 22 and 23. The shaft 20 drives the shaft 21 through the equal spur-gears 24, so that the rollers 8 and 9 are driven at equal peripheral speeds. The shaft 21 is connected with the shaft 25 by a pair of equal spurgears 26. The shafts 25 and 27 are connected by the spur-gears 2S.

` The pair of rollers 14 is arranged to elongate a mass of dough that is placed between them and to deliver the same down the inclined surface 29 to a point adjacent to the rollers 10 and 11, from which the dough is delivered upon the platform 30. Similarly the inclined surface 31 conducts the dough from the rollers 15 to the rollers 8 and 9, which deliver upon the platform 82. The platforms 30 and 32 are located immediately over their respective portions of the conveyer. The two pairs of rollers which operate on the same mass of dough are disposed at right angles to each other, and the inclined surfaces connecting the successive pairs of rollers are so arranged that the mass of dough will be elongated in one direction when passed through the upper set of rolls and will be elongated at right angles to the first elongation.

TOO

when passed through the second set of rolls. The successive forms of the mass of dough are shown by the outlines on the surfaces 29,Y 30, 31, and 32.

Power is supplied to the machine by a belt connected with the pulley 33 on the shaft 17. Said shaft is connected with a vertically-disposed shaft by means of the bevel-gears 34 and 35. This vertically-disposed shaft drivesV the conveyer mechanism below the platform 1 and is also connected by the pulley 36 and the belt 37 With the trimming mechanismJ. The trimming mechanism is carried by a bracket 38, which is mounted at the lefthand end of the table 1.

The operation of the device shown is as follows: The conveyer 3 is intermittently driven, so as to successively bring each of the rdelivered upon the platform 30.

pie-tins to a osition'of alinement with the trimming mec anism 5 and to stop for a predetermined interval of time whenever one of the pie-tins arrives at a position of alinement with said trimming mechanism. An operator stands at each side of the crust-rolling mechanism. The operator who is at the side corresponding to the bottom of Fig. 1 drops a lump of dough between the rollers 15 at regular intervals of time corresponding to the intervals of intermittent movement of the conveyer. The crust-rolling mechanism is continuously driven, and said rollers elongate the dough and deliver the same upon the surface 31 in a form somewhat like the outline there indicated. The operator then gives the mass a slight push toward the rollers A8 and 9, which elongate the dough at right angles to the direction of the iirst elongation and deliver the same in the form of a substantially circular disk u on the platform 32. The operator at the otiier side of the machine feeds the rollers 14 in a similar manner, and the dough is If we assume that the conveyer moves in the direction of the arrows on Fig. 1, then the series of operations is as follows: The pie-tins are placed upon the carriers at a point along the conveyer toward the left of the rollers 10 and 11. The operator at that side of the machine places the bottom crust in the tin when such tin stops in its nearest position at the right of the platform 30. The filling of the pie is placed upon the bottom crust while the pie-tin is 1n a position near the right-hand end of Fig. 1. Another operator places the top crust upon the pie when the same has passed the platform 32. The crust is trimmed at the trimming mechanism 35, and the pie is finally removed after passing said trimming mechanism, and its tin is replaced by another.

Ther compactness of the crust-forming mechanism and the relative arrangement of the conveyer, whereby the pie-tins are in a position to be operated upon at all times during their passage around the conveyer, makes it possible to provide room for the various operations which are to be performed in the manufacture of the pies with a minimum use of floor-space.

What we claim as our invention, and desire to secure by Letters Patent, is-
